Mystery Berry Jam

Mystery because we got these from our friends at Groundwork Organics, and no one was exactly 100% sure what they are. What we know for sure is this: they brightly burst with juicy tang and are just delicious. In fact, I am pretty convinced that they're purple raspberries, but it's too fun to think of them as mystery berries so we'll keep the name and have a little fun. Sound OK?

ingredients: organic mystery berries, cane sugar, lemon.
